Power Outage Preparedness: Generator Setup Guide
Most people buy a generator after an outage, vow to be ready next time, and then find the generator won't start when the next outage arrives. Preparation is a habit, not a one-time purchase. Here's the system that works.
Before You Even Buy: Calculate Your Load
List every appliance you must keep running: fridge, heating pump/boiler, medical equipment, a few lights, phone charging. Total those running watts. Add the highest motor start surge. Buy a generator with at least 20% headroom above that number.
Storage: Where to Keep Your Generator
Store in a dry, ventilated location — shed, garage corner, or purpose-built cover. Keep it elevated off concrete floors (damp rises through concrete and corrodes components). With fuel stabiliser in the tank, it can safely store for 12–24 months.
Build an Outage Kit
Keep these items next to the generator at all times:
- 5 litres of fresh petrol in an approved container (rotate every 3 months)
- Correct oil grade (see your manual) — 1 spare litre
- Heavy-duty outdoor extension cords (3× 25m, 12-gauge minimum)
- Multi-way socket board (surge protected)
- Battery-powered CO detector
- Generator manual
The 3-Month Test Run
Every 3 months: roll out the generator, check oil, add fresh fuel, start it, run a heater or lamp from it for 30 minutes. This tells you everything is working and keeps internal seals lubricated.
Outage Day Protocol
- Position generator at least 6m from any window or door
- Check oil and fuel
- Start in choke position, warm up 2–3 minutes
- Move choke to run position
- Connect load with extension cords or transfer switch
- Monitor CO detector inside
FAQ
How long will a generator power a home fridge?
A typical fridge draws 150–400W running. A 6,500W generator at 50% load with 3+ litres of fuel will run it for 6–8 hours. A dedicated 2,500W generator will run only the fridge for 10–14 hours on the same fuel.
